定时ping取返回值并绘图

　　前些天一个朋友有要ping交易所前置以及绘制成折线图的需求,帮忙做了两天,感慨颇多,故写篇博客记录一下.

实际需求

　　首先,我们的需求是,在window或者linux机器上定时执行ping + 网址 的语句,最终取到平均延迟,然后将这些延迟绘制成折线图.所以分析下来我们需要以下几个模块来实现这个功能.

需求分析

定时功能:

　　datetime模块

用window机器远程控制linux机器,并发送指令:

　　paramiko模块

绘制折线图:

　　matplotlib模块

window机器上取本机的ping数据:

　　subprocess模块

那么下面我们逐一分析这些模块,以及怎么样使用,完成最后的需求.

模块简介

datetime模块

相信我们都使用过这个模块,那么我们要实现每天定时来执行程序,就可以用以下方式来实现:

 

 

 

 

 

 

 

 

1

import datetime

2

import time

3

​

4

def main():

5

    while True:

6

        while True:

7

            now = datetime.datetime.now()# 这里可以取到系统的当前时间

8

            if now.hour == 6 and now.minute == 30:# 取当前时间的小时和分钟,这样每天到这个设定好的小时和分钟内的时候我们就会跳出这个内循环,进入到外循环,从而执行主函数

9

                # 当然设定时间我们也可以设定秒,但是其实设定到秒的情况下有可能无法进入函数,时间太短系统无法判定

10

                break

11

            if now.hour == 9 and now.minute == 30:

12

                break

13

            if now.hour == 12 and now.minute == 30:

14

                break

15

            if now.hour == 14 and now.minute == 30:

16

                break

17

            time.sleep(20)

18

        # 主函数

19

        time.sleep(60)# 这里加入睡眠60秒是为了让主函数不至于在这一分钟内一直执行,仅执行一次就好

20

​

 

 

subprocess模块

这个模块主要用于python调用系统的cmd窗口并返回结果,具体实现如下.

# encoding=utf-8

2

import subprocess # 导入模块,没装的话自己去pip install subprocess

3

import sys

4

​

5

# 常用编码

6

GBK = 'gbk'

7

UTF8 = 'utf-8'

8

​

9

# 解码方式，一般 py 文件执行为utf-8 ，但是cmd 命令为 gbk

10

current_encoding = GBK

11

​

12

popen = subprocess.Popen(['ping', 'www.baidu.com'],

13

                         stdout=subprocess.PIPE,

14

                         stderr=subprocess.PIPE,

15

                         bufsize=1)

16

​

17

# 重定向标准输出

18

while popen.poll() is None:  # None表示正在执行中

19

    r = popen.stdout.readline().decode(current_encoding)

20

    sys.stdout.write(r)  # 可修改输出方式，比如控制台、文件等

21

​

22

# 重定向错误输出

23

if popen.poll() != 0:  # 不为0表示执行错误

24

    err = popen.stderr.read().decode(current_encoding)

25

    sys.stdout.write(err)  # 可修改输出方式，比如控制台、文件等

折线图绘制的时候主要碰到了下面几个问题:

3

1. 标签和折线的名称不能使用中文

4

解决:导入一个字体模块或者不用中文,用全拼或者英文

5

2. 绘图时候要控制图层的大小

6

解决: 在刚开始绘图的时候加入plt.figure(figsize=(10, 8)),可以调整图层的大小,后面的(10,8)实际大小是乘以100,也就是1000*800的图片大小

7

3. 最后保存图片的时候保存jpg格式出错

8

解决:需要额外装一个模块,语句 pip install pillow

　　paramiko模块主要作用是用python来远程连接服务器,发送请求以及取数据,由于使用的是python这样的能够跨平台运行的语言，所以所有python支持的平台，如Linux, Solaris, BSD, MacOS X, Windows等，paramiko都可以支持，因此，如果需要使用SSH从一个平台连接到另外一个平台，进行一系列的操作时，paramiko是最佳工具之一。
